The day the ceiling collapsed Genesis sent a worker round to clear out the debris and fix the leak, but the ceiling has been left exposed for weeks, and the light has been dangling from the large hole on its wire.

“I’m an old-age pensioner and I’m ill,” Joy added. “I’m on oxygen and they were telling me to claim it on my insurance.

“As far as I’m concerned it’s their job to fix it because it’s their property upstairs and that’s where all the water was coming from.

“I’ve been complaining every week. They have had me waiting on the phone for an hour. I’ve got no light, the light is hanging down.”

Genesis told the Gazette it would be arranging for a worker to go back round and cover up the ceiling this week, though Joy said she had heard nothing.

A spokesperson for the housing association said: “The flat is not a Notting Hill Genesis property, the resident there is a private leaseholder.

“However, the flat which was the source of the leak is leased by us from a private landlord and used to provide temporary housing to those in immediate need.

“While there is no responsibility for the landlord of the flat above to sanction repair work on the property below, given the circumstances they have arranged for a contractor to attend next week and fix Ms Saunders’ ceiling.”
